Teespring and squarespace

Hi,

I've seen several posts on here for people trying to set up e-commerce using Teespring. When people try to connect the domain to SquareSpace they get connection errors. Of all of the posts I've seen in the forums I've seen no resolutions.  I'm trying to do it now and I am getting nothing but errors. I try to use 

in the A field. The only thing that has even come close to connecting is the direct link to my storefront, which is not correct. I have no place to enter the IP manually.

Any help? Please?
